Mexican man with world’s longest penis is accused of exaggerating as scan shows it is actually only SIX INCHES long – a foot shorter than he claims.

The man who claims to have the world’s longest penis has been accused of exaggerating its size with a doctor saying that it is actually only six inches long.

Robert Esquivel Cabrera 54, from the northern town of Saltillo who is said to have worked on his penis by stretching it using weights, boast of 18.9inch manhood and cannot have sex because of the size.

But now radiologist Dr. Jesus Pablo Gil Muro, who examined Mr. Cabrera, said that the man refused to take off all of the bandages around his penis and wouldn’t let the doctor see the skin.

Dr. Muro also claimed that Mr. Cabrera was ‘obsessed’ with his penis length, with the 54-year-old stretching his penis with weights.

Jonah Falcon, 47, from New York was the previous record holder. He is famed for having a 13.5-inch penis and accused Mr. Cabrera of being a fraud.

He believes his challenger has been weighing his genitals down with weights and so the record shouldn’t count.

Because he stretched his penis and doctors like Dr. Muro say that his penis is actually only six inches long, the Guinness Book of Records refuses to recognize his ‘achievement’.

Medics have urged Mr. Cabrera to have a reduction so he will be able to function normally and have children, but he has refused.

Mr Cabera added: ‘I am famous because I have the biggest penis in the world. I am happy with my penis, I know nobody has the size I have.’

Mr. Cabrera the self aclaimed world longest penis who has since been registered as a disabled since he can no longer have sex is currently receiving government handouts, despite refusing to get a reduction because he hopes to find work in the American porn industry.
